Memory IC Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm packaging type and tape/reel specifications. Ensure the operating voltage range of 2.3 V to 3.6 V aligns with your system design. Confirm the SOIC-N 8-pin package dimensions match your PCB footprint requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 1 Mbit capacity is required for non-volatile code or data storage in space-constrained designs. The 104 MHz speed suits applications needing moderate read performance. Consider the -40°C to +85°C range for general commercial use; higher temperature variants may be needed for harsh environments.

Memory IC Part Context

This part belongs to the AT25DN series of Serial NOR Flash memories from Renesas. These devices are designed for high-reliability applications requiring efficient code execution and data storage. The series typically offers low power consumption and robust security features suitable for modern embedded electronics.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the AT25DN family, such as the AT25DN512C, if capacity adjustments are acceptable. Verify that any substitute maintains the same SPI mode support and voltage range.
